This includes installing apps from trusted sources only, avoiding email scams, and refraining from clicking any suspicious links.

Uninstall third-party apps. Make sure apps are always from a reputable company. Apps that are marketed as "cleaning" or "optimizing" are usually hidden viruses, and you should uninstall them immediately. Other questionable apps include apps with few to no reviews, or apps with a burst of 5-star reviews in a short period of time.
- On iOS, tap and hold the app icon. Tap Delete App, and then Delete App again.
- On Android, open the Google Play Store. Tap your profile picture → Manage apps & devices → Manage → tap the app name → Uninstall.^{[1]XResearch source}

Smartphones can cast its screen to another device using AirPlay or Screen Mirroring. In most cases, this is usually initiated by the device owner. However, if you don't want to accidentally cast your phone, you can disable Bluetooth and Wi-Fi. AirPlay and Screen Mirroring rely on this to transmit the signal to another screen, so it won't be able to do so unless you turn them on again.

5

Change your passcode.

Update your phone's passcode. If you leave your phone in places that are easily accessible, you should update your passcode regularly. This is especially important if you have a passcode that is easy to guess, such as your birthday. Using a more complex passcode can keep others out of your phone.
